Watch the following short video, Becoming An Organized Person by Peter Walsh.
Your English listening will improve; Peter Walsh speaks clearly and directly.
It will take less than two minutes of your time.
More than this, I hope that watching this video will help you if you need to organize your life more efficiently and stop wasting time. We all tend to procrastinate (put things off to do ‘later’ rather than do them now). Do you do this with your studies? I know that I do it with housework! Note what he says about To Do Lists, Caring for Yourself, Later, Decisions Delayed, and Clutter.
